ThunderMax pinging Twin Cam 96
If you have any suggestions, please provide some detail, I am a rookie at the TMAX. I did make one small adjustment to timing and it didn't fix the pinging. All I did was bring the timing down 1 notch on the overall timing section in the 2 to 4 K rpm section.
After that....take more out of the front cylinder in the problem range and maybe add a little fuel
Also, give it time to tune....most say 300-500 miles but I think it's more like 1000-1500 in my experience
What has changed recently? Are you using the same type of gas from the same location? Was the bike running good and then the pinging started? When did it start? What changed just before it started?

Do you have the best map for your configuration? You can check that by ensuring you have the latest software update and reviewing all possible choices.
Have you checked for exhaust leaks? Are your plugs good?
Already asked about gas, but what about altitude? Where are you riding?
Finally, I'd call Zippers vs email, I've never had a problem with support via telephone (I've called them 3X and recieved patient support each time. Look at page 102, there is a caution about independent adjustment of the rear cylinder timing without dyno data.

PS: Look at pages 102-104 as well.

Twin Cam 96 ci, Stock throttle body, Stock Cylinders, Stock Pistons, Stock Cam, Stock HD FL Head Pipe, Hi-Flow filter 2.75" deep (I have the K&N system), KW HP+ Mufflers ( I have SE slip-ons) witha date of 05/01/2007, which was the latest date at the time of installation.
I called them because they did not list a SE slip-on muffler, which I thought was strange, apparently they don't list that one but they said the Krome Werks muffler was equivalent to that muffler.
So, I feel that I can't really find a better map than this one. I also find it strange that no one else has had pinging under heavy throttle, am I the only one that gets on this thing? It doesn't ping in normal easy use, just when I really give it hell.
